Abstract

액정 표시장치 등과 같은 디스플레이 장치에 채용될 수 있는 광학 시트와, 이를 구비한 백라이트 유닛 및 디스플레이 장치를 개시한다. 광학 시트는 베이스층과, 베이스층 상에 요철 패턴으로 형성된 패턴층, 및 패턴층 상에 패턴층의 높이보다 높게 돌출되게 형성되고 불규칙하게 배열된 복수의 칼럼들을 구비한다. 이러한 광학 시트의 구성에 의하면, 다른 광학 시트와 적층될 때, 스크래치 및 패턴층의 손상이 방지될 수 있고, 휘도 향상을 도모할 수 있게 된다. 그리고 백라이트 유닛과 디스플레이 장치는 이러한 광학 시트를 적어도 하나 구비한다.
